tsdemux no more pads

[Rand Graham]

Hello,

I am trying to transcode a video that is using a transport stream container. I can decode the video using one pipeline the success case. When I try to name the demux video I have a failure that says no more pads.

Can someone tell me what is going wrong?

Failure Case:

gst-launch-1.0 -v filesrc location=uhd.trp ! tsdemux name=demux demux.video_0 ! queue ! h265parse ! omxh265dec ! nvvidconv ! 'video/x-raw(memory:NVMM), width=(int)1280, height=(int)720, format=(string)I420' ! omxh264enc profile=8 ! qtmux name=mux ! filesink location=uhd1280x720.mp4
